Formula optimization and physicochemical analysis of nutritious formula powder of bamboo shoots of Chimonobambusa quadrangularis

The dosages among bamboo shoots of Chimonobambusa quadrangularis as the main raw material, ingredients, auxiliary materials were optimized based on single factor and orthogonal experimental method. The physical properties, the mineral elements contents by ICP-MS and the nutrient contents of nutritious formula powder were determined in order to develop a nutritious formula powder of bamboo shoots product with good taste, nutrition balance and a certain health function. The results showed that the optimal formula was determined as follows:bamboo shoots 16 g, Eucommia ulmoides staminate flower 8 g, Jerusalem artichoke 12 g, Chinese yam 12 g, Oat flake 8 g, white granulated sugar 8 g, xylitol 8 g, and malt dextrin 8 g.The results of the physical properties indicated that as all the materials were grinded to 100 mesh number, the bulk density was not only the minimum, the water holding capacity and swelling capacity were but also the highest. Its wetting ability and dispersibility had no significant difference(p<0.05)when the water temperature respectively were at 80℃ and 90℃, so 80℃ was the optimal water temperature of mixing effect. Comparison of nutrient content between the nutritious formula powder and ingredients, as well as the mineral element content between the powder and single bamboo shoots, it was showed that there must had a good effect on balanced nutrition and supplementing mineral elements.
